Benefits of technology

[0014] It is still another object of the present invention to provide an information storage medium that allows a file to be more efficiently preloaded by providing information on a type of a file to be preloaded so that each content of the file can be reproduced seamlessly in a display window defined by a markup language document, and an apparatus for and a method of reproducing the information storage medium.
[0015] It is yet another object of the present invention to provide a method of guaranteeing that sufficient data remains in a memory even though a preloading function is performed during reproducing a content stored in the memory.

Problems solved by technology

In that case, exhaustion of the buffered data may happen.

1.0\\EN”“http: / / www.dvdforum.org / enav / dvd-preload-list.dtd”-->

[0117] The above text data is the XML document and includes the data amount (size), the paths, and the types of the files to be preloaded.

[0118] The API for the preloading / discarding functions used in the above script program code can be explained in detail as follows.

[0119] 1. navigator.Preload (URL, flag)

[0120] It is the API that reads the specified file to be preloaded to the second memory 3. The used parameters specify the location information of the preload list file or the file to be preloaded.

[0121] URL: Path of the preload list file or the path of the file to be preloaded.

[0122] flag: When URL indicates the preload list file, flag is 1, and when URL indicates the file to be preloaded, flag is 0.

[0123] return value: If the preload performing is successful, “true” is returned. If the preload performing fails, “false” is returned.

Abstract

An information storage medium which contains preload information, a reproducing apparatus and a reproducing method. The information storage medium includes AV data and a markup language document displaying the AV data which is decoded and reproduced and including preload information that allows the reproducing apparatus to read a file to be preloaded and to store it into a memory. The information storage medium contains the markup language document to prevent a video picture from being interrupted when the AV data recorded in the DVD is reproduced and displayed through the markup language document. The reproducing apparatus and reproducing method reproduce information from the information storage medium.
